A payment processor for providing a payment service includes a transaction processor to process a transaction request. An application programming interface links a merchant to the transaction processor based on an identifier. A merchant center, located between a gateway and a point of sale device of the merchant, queries a database for information associated with a buyer and the merchant based on information received from the point of sale device, to generate the transaction request based from merchant transaction data received from the point of sale device and the information associated with the buyer and the merchant received from the database, and to communicate the transaction request to the transaction processor. The transaction processor also communicates information associated with the transaction request with the merchant based on the identifier. |
